The Canada international was forced out of Saturday's stormy derby clash following a challenge with Sheffield United captain Chris Morgan, and his condition later deteriorated. "He got caught in the face with an elbow," said the Barnsley manager Simon Davey. "He couldn't move his neck. His neck was stiff and his cheekbone's not in the same shape it was when he started the game. "At the time I thought when somebody raises an elbow and catches you in the face, it usually is a red card, but you're talking about playing Barnsley and at the moment that doesn't happen." Morgan, a former Barnsley defender, was booked for the incident. "Sheffield United are saddened and concerned to hear that Barnsley striker Iain Hume is being monitored in a high dependency unit following last Saturday's fixture and we wish him a speedy and full recovery," said the Blades in a statement. A high dependency unit offers a level of care between that of a general hospital ward and an intensive care unit. The clash was one of many in a highly-charged Yorkshire derby. United's Ugo Ehiogu and the Tykes' Anderson Silva were sent off in the first half for throwing headbutts at each other, and Barnsley are today appealing for information after coins were thrown on to the pitch from the CK Beckett Stand at Oakwell.
